It is possible to also get a bad picture if the signal strength of the TV transmitter is too high. An attenuator inserted in the antenna lead-in wire may be used if the television receiver displays signs of overload in the RF front end. Strong out-of-band signals may also affect television reception and may require band-pass filters to reduce ...
Canada had a similar analog TV termination date set to September 1, 2011 (except in some remote northern regions). [citation needed] It was feared that the US switch-off would cause millions of non-cable- and non-satellite-connected TV sets to "go dark". Viewers who did not upgrade, either to a television with a digital tuner or a set-top box ...
In the United States, UHF stations gained a reputation for local ownership, nonprofessional operations, small audiences and weak signal propagation. While UHF-TV was available to American TV broadcasters in today's form since 1952, affiliates of the 1950s four largest American TV networks (NBC, CBS, ABC, and DuMont) preferentially transmitted ...
The near–far problem or hearability problem is the effect of a strong signal from a near signal source in making it hard for a receiver to hear a weaker signal from a further source due to adjacent-channel interference, co-channel interference, distortion, capture effect, dynamic range limitation, or the like.
USA TODAY 2 hours ago Helicopter black box and 41 bodies recovered; Army identifies 2 soldiers: DC crash live updates. While authorities focus on the cause of the US's deadliest aviation disaster since 2001, families are mourning their loved ones. Here's the latest.
The ATSC signal is more susceptible to changes in radio propagation conditions than DVB-T and ISDB-T. It also lacks true hierarchical modulation, which would allow the SDTV part of an HDTV signal (or the audio portion of a television program) to be received uninterrupted even in fringe areas where signal strength is low.
Signal reception is invariably done via a superheterodyne receiver: the first stage is a tuner which selects a television channel and frequency-shifts it to a fixed intermediate frequency (IF). The signal amplifier performs amplification to the IF stages from the microvolt range to fractions of a volt.
